Kyzteke - Rodeio asked if one sees many TWH in endurance. I answered no…because in the years I’ve been doing endurance, I think I’ve only seen one! I’ve seen RMH, Pasos, gaited 1/2 breds - but they are all in the extreme minority, and they all tend to hang at the back. Rodeio didn’t ask if they excelled at the sport, so I didn’t volunteer an answer to that non-query.
Candyappy - yes, ALL endurance rides in the US (except those run by the FEI) are under the governance of the AERC. AERC offers Limited Distance (rides 35 miles or less), and endurance (one day rides 50 miles to 100 miles in length). Limited Distance and Endurance have similar rules with a few exceptions.
The FEI also offers FEI endurance. FEI rides are generally only 100 mile rides, although some are now starting to offer 50 mile rides to qualify riders for higher levels. FEI rides are designed to help qualify horses and riders for the international endurance scene. For 2011 there are 9 FEI rides listed in the US. Compare that with several hundred AERC rides for 2011 - these being just the early sanctions which will increase X3-4 by the time summer rolls around.
In the US there are relatively few FEI rides compared to AERC rides simply because AERC was here long before FEI, is our official governing body, and offers a large open door policy for ride types, distances, awards, vetting procedure, etc. The vast majority (99%) of endurance riders in the US do not want to compete internationally, are not FEI members, and find more freedom and choice in an abundant offering of AERC rides. Same goes with endurance ride managers - they have far more freedom under AERC in choosing trails, ridecamps, distances, amenities, vetting procedures, number of holds, even parking options.
An FEI ride can also be AERC sanctioned if the ride wants to bring in more income (AERC sanctioning=more riders) and if they want to allow riders to accumulate AERC points and miles. However, FEI has some rules different than AERC - they impose certain conditions on FEI riders, the trail, finish criteria, times to present, even down to rules on where competitors may park (separate area and closest to vet check) that AERC does not. These stricter conditions often are a headache for the Ride Management.
If anyone is interested, the AERC website has statistical information on the breeds that have been recorded in AERC Limited Distance and endurance rides over the decades. Quite fun to browse through and see what breeds have been out there on the trail.
